Minimizing Instability After Revision Total Hip Arthroplasty
摘要
Dislocation is a common mode of failure and indication for reoperation after revision total hip arthroplasty. Numerous technical strategies can be employed during revision surgery to reduce the risk of instability postoperatively. Basic tenets of revision surgery include optimizing combined anteversion, hip length, and offset. One can consider dual mobility or constrained liner constructs with their respective advantages and disadvantages. Additional considerations come into play when retaining components. Resection arthroplasty or “Girdlestone” represents a last resort when acceptable stability cannot be obtained.
